` Letters Patent No. 95,259, dated September V28, 1869,

i IMPRovED Mop-HEAD;

The Schedule referred to in these Letters Patent and making part o f the same.

'To all tch-gm it may concern j Be it known that' I, H..\O. 'PA1es0Ns, of Dexter, in the county of Penobscot, and State of Maine, have inl vented a new and useful Improvement in Mop-Heads;

`andI do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable `those skilled in theart to make and use the same, reference being had to the accompanying drawings, forming part ofthisspeciiication.

rlhis invention relates` to an improvement ,in the method of`holding the yarnl orrags in mops, or in the construction of the -mopfhead; and

It consists in providing the `jaws of the head wit-h teeth forholding the rags, and in the method of forcing and holding the jaws together on the rags, as I will proceed to describe. l

'The drawing represents a longitudinal -view of they ,p head with'the mophandle attached.

A is the handlerr y B is the part of the head to which the handle is at` tached, as seen in dottedlines at C. i

ID is' themovable part of the head, which slides on the handle, and which is gnided by the grooved end of the part 13,1(01 the upper jaw,) as seen at e e, in*- the drawing.

Fis the lower jaw. f 4 The red coloring represents the rags, which form the mop or swab. j 4 j The lower jaw E is convex, Vor rounded o'nits upper-side, and provided with teeth,as seen in the draw- 'Ilhe upper jaw B is concave, and also provided with l teeth, which are seen in dotted lines in the drawing.

`'Ihese teeth penetrate the rags, ,or other material forming the mop, and serve to prevent their slipping from the jaws; j

For the purpose of forcing the two jaws toward each other, and thereby squeezing the ragsbetween them,

I placca double tubular cam, Gebetween the tubular j partsof the head, or the parts marked h and i.

This double cam revolves onthe handle, andthe l `partsh and i are madeso as to correspond where they come in contact withit.' j y It will be seen, thatby turning the cam to the right,

i the jaw F willbe forced upward and the'jaw'` B will be forced downward, and the rags will be squeezed between them as much as maybe desired.

or nearly so, lthe teeth in the'jaws will nearly or quite come in contact with each other.

v The middle portion of the cam G is formed with concave circles, or in any other shape to allow of'a good hold for the hand in turning it.

For the purpose of holding it in any desired position, one of itsedges (where) it comes in ,contact with i)-is serrated, or formed with depressions andpi!ojections, as `,seen at J, and on the edge of the lpart i, as seen at o, there is a single projection, which fits into the depressions in J, and the elasticity of theI rags keeps these parts engaged with each other, `and pirevents the cam fromturning back when the mop .is in use. v

I am aware that a single rotary tubular cam has been .applied to the handle, and to operate the movable jaw of a mop-head, the same being as represented in the patent of' Randlett, dated November 15, 1858; therefore I make yno claim thereto.

.I employ 'a duplex tubular cam, as explained, provided with a rack or series of notches on one inclined edge, .to operate with a tooth and oblique helical edge of the stationary jaw, and also with a corresponding Obliquity applied to or extending from the yoke of the movable jaw.- The duplex cam, formed and arranged with the two oblique surfaces against which -it oper ates, -has important advantages over the single cam, as it allows the jaws to open double the distance, so as totake in athicker mop, and it enables the rack to be employed, whichl could not be well used to advantage vwith a single cam, formed to produce, by the same degree of rotary movement fof it, the same degree of movement of the jaw; for, with the single cam the obliquity, under such circumstances, would be too great for, the rackto beV used to good advantage.

I therefore claim as my improvement-a The combination of the toothed jaws B F, tubular parts h i, and double cam G', all constructed and a1'- ranged to operate as herein described, for the purpose specified.
